JAMES H. PEIBOE, OF BLOUNTSVILLE, INDIANA, ASSIGNOR OF ON E-HALF OF HISRIGHT TO JONATHAN ROSS, OF SAME PLACE.

CUL T|VATO R.

SPECIFICATION formingpart of Letters Patent No. 227,383, dated May 11,1880.

Application filed February 9, 1880.

To all whom it may concern Be it known that I, JAMES H. PEIRcE, of thetown of Blountsville, county of Henry, and State of Indiana, haveinvented certain new and useful Improvements in Cultivators, of whichthe following is a specification, reference being had to theaccompanying drawings, which are made a part hereof, and on whichsimilar letters of reference indicate similar parts.

Figure 1 is a top or plan view of an imple ment embodying myimprovements in position as when the wheel-spindles are in line witheach other. Fig. 2 is a similar view in position as when one wheel is inadvance of the other. Fig. 3 is a rear elevation as seen from the dottedline 2 'z, the plows not being shown. Fig. 4 is a longitudinal verticalsection on the dotted line or w.

In said drawings the portions marked A represent the wheels of the plow;B, frames constructed to meet the requirements of my invention, attachedto and supported by the wheel-spindles; O, draft-rods constructed in theform of a light frame-work and attached by pivots c to the frames B D,an arch connecting the two frames B; E, hounds reaching forward from theframes B to form a connection for the tongue 5 F, a tongue, which isconnected at the proper point by the pivot f to the point of the houndsE, and the rear end of which passes between the cross-bars E, thusproviding for free lateral movement, and G the plows.

The object of my invention is, first, to pro duce a corn-plow in whichthe vertical movement of the wheels in passing over obstructions or intoruts shall not operate to materially disturb the plow itself or cause itto run unevenly in the ground; second, to attach the plow directly tothe draft-bars, and not to the side frames; third, to so construct theframes, arch, and tongue that the wheels and plows may pass and repasseach other in the direction of their progression, as indicated in Figs.1 and 2, without throwing the front end of the tongue from side to side5 and, fourth,

to allow such relative changes of the position of the parts to takeplace without subjecting any of them to any unusual strain.

The first and second of these objects I attain admits of the wheelsrising and falling a considerable distance Without materially affectingthe position of the point of the plow-beams or the plows attachedthereto.

The third and fourth objects I attain by attaching the arch D to theframes B in such a 6 5 manner that the latter will pivot freely on theformer, and by pivoting the tongue F to the point of the hounds E insuch a manner that while it is horizontally rigid therewith the lateralrelative position will freely change as the point of the tongue is movedsidewise or the Wheels advance and recede relatively to each other.

By changing the downwardly-projecting parts of the arch D from one setto another of 7 5 the holes (I d in the top portion of the frames B Bthe distance between said frames can be varied to suit the width ofrows, and the distance between the plows can be varied, so as to plowcloser or farther from the corn, by

moving the point of attachment on the bars 0.

Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a corn-plow, the draft bar or frame 0,

loosely pivoted to the side frames, B, by the horizontal pivots c,'to apoint to the rear of the wheelspindles, and having the point of I powerattachment in front thereof. while the plows are attached to said bar orframe at an intermediate point, all substantially as shown anddescribed, and for the purposes specified. 2. In a corn-plow, the wheelsA, frames B,

arch D, hounds E, tongue F, loosely-pivoted bars or frames 0, and plowsGr, all arranged and operating in combination with each other,substantially as shown and specified.

3. In combination with the side frames of a cornplow loosely pivoted onthe arch and lnwing the draft bars or frames loosely pivoted thereto, atongue pivoted in the manner shown, said several parts being thu'sconstructed to allow each of them to occupy varying relations to theothers, all substantially as 10 shown and set forth.

In witness whereof I have hereunto set my hand and seal at Blountsville,Indiana, this 2d day of February, A. D. 1880.
